Rajini and Rajan have decided to start a ?maly. Rajan
has normal .vision but he has a brother who has a rare
inherited form of blindness. Neither of Raj an?s parents
nor his two sisters are blind. Rajini has two brothers and
two sisters with normal vision and neither of her parents
are affected. Draw a pedigree to illustrate the situation
using the standard symbols for males, females, affected,
unaffected, carriers etc. Rajni and Rajan would like to
have two children. What is the probability'that either of
their children will be blind? What is the probability that
either children will be carriers? Explain your answers.
